[0002] When installing a combiner box, its bottom is usually required to be at least 1 meter above the ground, so a bracket is needed to suspend it in the air. Currently, multiple locking parts are mostly used to lock it up and down to ensure that the combiner box is stably installed on the bracket.

[0003] Since the combiner box is suspended in the air, when its position needs to be adjusted during the installation phase, multiple people are required to open its locking parts and temporarily lift the combiner box to find a suitable position and then lock it. During the maintenance phase, since the combiner box is high and inconvenient for workers to operate, it also needs to be lowered, which requires multiple people to open the locking parts, lower it, and then lock it. This increases labor costs, is very inconvenient to operate, and reduces work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0017] like Figure 1-3 As shown, a photovoltaic junction box installation structure includes a connecting body 1, which is a hollow cavity with an opening at the bottom. A hanging rod 2 is connected to the upper part of the connecting body 1, and also includes a limit plate 3, a clamping assembly 4 and a lifting and adjusting assembly 5. The limit plate 3 is fixedly connected to the upper part of the outer wall of the connecting body 1, and the limit plates 3 are symmetrically arranged with the connecting body 1 as the center. The symmetrical limit plates 3 are arranged parallel to the side walls of the adjacent limit plates 3 of the connecting body 1 and form a supporting surface. A plug hole 6 is opened in the limit plate 3, and the clamping assembly 4 passes through the plug hole 6 and is movably connected to the supporting surface of the connecting body 1. The lifting and adjusting assembly 5 is arranged at the bottom of the connecting body 1, moves along the opening direction of the connecting body 1 below the connecting body 1 and adjusts the height of the photovoltaic junction box.

[0018] like Figure 1 and Figure 3 As shown, in order to improve the convenience of positioning the junction box after installation, the clamping assembly 4 includes a stud 7, a connecting ring 8, a limiting rod 9 and a plug plate 10. The stud 7 is rotatably connected to the side wall of the positioning plate on one side of the adjacent symmetrical connection body 1, and the connecting ring 8 is threadedly connected to the outer wall of the stud 7. The end face of the stud 7 away from the connection body 1 is connected with a stopper 11 for limiting the movement and adjustment of the connecting ring 8. One end of the limiting rod 9 is fixedly connected to the outer wall of the connecting ring 8, and one end of the plug plate 10 passes through the insertion hole 6 and is slidably arranged in the insertion hole 6. The other end of the plug plate 10 is fixedly connected to the end of the limiting rod 9 away from the connecting ring 8. The stud 7 is rotated to adjust the position of the connecting ring 8 along the axial movement of the stud 7. The plug plate 10 is driven to slide and adjust in the insertion hole 6 by the limiting rod 9 to adjust the distance between the limiting rod 9 and the positioning plate. When the junction box is installed and raised, the inclined limiting rod 9 limits the upper corners of the junction box to meet the limitation of junction boxes of different thicknesses.

[0019] like Figure 3As shown, in order to adjust the height of the combiner box so that the combiner box can meet the requirements of maintenance, lowering and ascending installation, the lifting and adjusting assembly 5 includes a fixed plate 12, a cylinder 13 and a support plate 14. The fixed plate 12 is fixedly connected between the inner side walls of the connecting body 1, the cylinder 13 is fixedly connected to the bottom wall of the fixed plate 12, the telescopic end of the cylinder 13 is telescopically adjusted along the open end of the connecting body 1, the support plate 14 is fixedly connected to the telescopic end of the cylinder 13, and a slide rod 15 is slidably connected inside the connecting body 1. The slide rod 15 is symmetrically arranged with the cylinder 13 as the center, and the bottom of the slide rod 15 passes through the fixed plate 1 2 is fixedly connected to the upper wall of the support plate 14, the slide bar 15 is in sliding contact with the fixed plate 12, the upper end of the slide bar 15 is fixedly connected to the limit block 16, and the upper part of the support plate 14 is provided with a limit column 17 away from the connection body 1 on the side, and the limit column 17 is symmetrically arranged, and the telescopic end of the driving cylinder 13 is telescopically adjusted to drive the support plate 14 to move up and down at the bottom of the connection body 1 and lift the junction box. When the support plate 14 moves up and down, the internal slide bar 15 slides in the fixed plate 12 to increase the strength of the connection between the telescopic end of the cylinder 13 and the support plate 14, and the limit block 16 is used to limit the bottom of the junction box.

[0020] Among them, through holes 18 are opened on both sides of the upper and lower ends of the end surface of the plug plate 10 for fixing the device, increasing the bolt connection positioning points of the device, and improving the connection stability.

[0021] During specific use, the operator suspends the device through the hanging rod 2. In the initial state, the cylinder 13 is in the extended state, and the support plate 14 is at the bottom. The junction box is placed on the support plate 14, and the cylinder 13 is driven to contract. The support plate 14 rises, driving the junction box to rise. According to the thickness of the junction box, the stopper 11 is rotated, and the stud 7 is rotated at the same time. The connecting ring 8 is adjusted along the axial movement of the stud 7, and the plug plate 10 is driven to slide and adjust in the plug hole 6 through the limit rod 9, so that the distance between the limit rod 9 and the positioning plate is approximately the same as the thickness of the junction box. When the support plate 14 continues to drive the junction box to rise, the upper corner of the junction box is inserted between the limit rod 9 and the positioning plate. At the same time, the limit rod 9 limits the junction box door to prevent the box door from opening, and the plug plates 10 on both sides limit the two sides of the junction box to achieve the height and position fixation of the junction box after installation;

[0022] When maintenance is required, the driving cylinder 13 is extended and the support plate 14 is lowered, so that the combiner box is lowered in contact with the supporting surface, the combiner box is separated from the limit rod 9, and the box door is opened for personnel maintenance, which effectively improves the convenience of installation and maintenance of the combiner box.
